The relationship between intelligence and brain size, both among people and between various species, has never been precisely well defined. People often believe that their outstanding psychological capacities must mean that they are superior to all animals as far as brain size is concerned. However, it is not true since whales and elephants have much bigger brains than humans and humans have the same brain-to-body mass proportion as mice do.

Here are a number of ways by which the brain size can be determined:

Encephalization remainder: Since it would be against human instinct to admit loss and defeat, researchers have created a measure to determine the brain size called the encephalization remainder. It is the proportion of actual brain mass with respect to the anticipated cerebrum mass for the animal s size (based on the suspicion that bigger animals require somewhat less brain matter with respect to their size, compared to little animals). By this metric, human beings prove to be the best, with an EQ of 7.5 outperforming the dolphin's 5.3 and the mouse's 0.5.
IQ testing: Without a solitary and evident method for measuring intelligence, some improved tests like IQ (Intelligence Quotient) are by and large acknowledged as a moderately decent working device. IQ estimations are not without issues, and there is a great deal of criticism about their significance. IQ testing uses government sanctioned tests, for example, the WAIS III (Wechsler Adult Intelligence Scale). The normal IQ is somewhere around 90 and 110. The scores beneath the normal may demonstrate changing degrees of pathology, for example, marginal intellectual function, or mental hindrance of different severity. Over the normal range is regularly connected with knowledge, splendour, talent, or genius. However, as with computers of a few eras, size and intellect do not precisely relate. Present day portable computers weighing around one or two kilogrammes can store more data and perform a greater number of assignments than supercomputers from the 1980s that used to possess expansive structures. This is a contrast amongst quantity and quality. Numerous scientists now hold the view that it is not the whole brain, which is bigger in a human with a higher IQ, yet rather certain zones that are denser and might be bigger. A fascinating late revelation is that these ranges can be expanded in size and enhanced in usefulness during the course of our life.
NeuroplasticityIt refers to the dynamic procedure of repair and maintenance that our brains are continually experiencing. We are conceived with around hundred billion neurones, yet lose around two hundred thousand a day to a procedure called pruning. As we develop and grow, pathways in the brain that are not required are detached, and the neurones pass on. However, in a compensatory procedure, new neurones are delivered and more detailed associations are built up between neurones that are more dynamic. This is the procedure of de-cluttering, in which our brains develop to work at most extreme effectiveness. If you wish to discuss about any specific problem, you can consult a Neurologist.

Brain Size - How It Is Related With Intelligence?

Your mother has often yelled at you for playing video games for long hours, but obviously you haven t paid heed to it. Such is the obsession with video games that they don t let you rest unless you have championed all the levels in the virtual interface. Here is the source of all problems. Studies have revealed that video games have a direct relation to neuropsychiatric problems. As a result, many health experts across the world consider video game as a kind of health abuse.

People who play action-oriented video games are at higher risks. The more you indulge in these kinds of games, the more they are going to affect the hippocampus section of your brain. It is that part of the brain which is considered to be the centre of your nervous system, memory and emotion. Reduced hippocampus volume may make person vulnerable to multiple neuropsychiatric complications. Let us see some of the signs, which may indicate the onset of certain complications arising from an over indulgence in these games.

1. You spend hours on the computer or related gaming devices and devote lesser hours for your family and friends

2. You get agitated when someone stops you midway through the game

3. You become socially isolated and show signs of occasional mood swings

4. You are unable to keep a track of time once you start playing

5. You repeatedly neglect your studies, resulting in a dip in performance at school

Why does this happen?

All of the above signs indicate that sooner or later you might develop neurological problems. When you spend an excessive number of hours on playing and navigating through the games, the  hippocampus  portion of your brain shows signs of decreased gray matter. As a result, the volume of the hippocampus shrinks, causing severe nerve related disorders such as schizophrenia, Alzheimer s disease, dementia, depression, and overall general stress.

One of the biggest reasons behind this is a lack of self-control. Most of the video games will encourage you to steal cars, run away after a theft and kill your enemies. Moreover, if you succeed, you are rewarded. This naturally unleashes a blatant urge for the gratification of all these awkward desires in your real life too. Hence, once you are encountered with the reality, you tend to show violent behavior.

Can Playing Video Games Cause Neurological Problems?

Obesity is the new-age lifestyle disease with multiple ramifications. While its effects on the physical aspects are very evident, the damage it does to the brain are more severe, though not obvious. Read on to know some harmful effects of obesity on the emotional well-being.

Leads to binge eating: There is a certain pleasure in eating sugary and fatty food, and this is lost with depression. Therefore, to get that emotional satisfaction, people tend to eat more chocolates, cookies, milkshakes, and other weight-accumulating food items, which further add to obesity. Greater the weight gained by a person, lesser the response or happiness from such food products.
Increases impulsivity: The area of the brain known as orbitofrontal cortex, which is in charge of controlling impulsivity, shrinks in obese people. This results in people eating more impulsively.
Affects immunity: Obesity is a major cause of inflammation, leading to damage in certain parts of the brain. This impairs the immune system, making the affected person more prone to infections and tissue damage. This leads to increased chances of diabetes, heart disease, stroke, sleeping disorders, eating disorders, etc. The chemical known as C-reactive protein increases as seen on MRIs in obese people, and which is usually seen in patients with chronically increased inflammation.
Effects on memory: As the BMI increases, there is a decrease in scores of memory tests. This effect is more obvious in women after menopause. With increased fat accumulation, more hormones are released, which affects the memory. Increased inflammation also affects cognition and memory.
Increased risk of dementia: With more belly fat accumulating, there is extra stress on the body to burn the visceral fat. This reduces brain size and causes certain hormones to release, which further affects the body s ability to remember things. It has been proven that people with smaller brain size are at greater risk for developing dementia.
Weight loss stress adding to more stress: When obesity sets in and the BMI goes up, there is an added pressure to lose weight, which further ups the stress levels. During these dieting days, the brain is constantly alert and finds ways to eat more. This also leads to excess eating. Moreover, there are indications that there could be genetic changes during this phase, which may leave a permanent mark in the person s composition.
Depression: When a person is not happy with their reflection in the mirror, the chances of feeling good and happy are very less. In this age, where aesthetics plays a major morale booster, an obese image staring back does not help at all.
So, if you have a risk of obesity, watch out. It is not just how you look, but how you feel is also altered.

How Physiotherapy Can Help with Neurological Disorders

Neurological disorders are problems with any one or a combination of the central nervous system or any of its peripheral systems such as cranial nerves, neuromuscular junctions, and the autonomic nervous systems among others.

Some extreme examples of neurological disorders are:

- Dementia
- Alzheimer's disease
- Parkinson's disease
- Epilepsy
- Disorders brought on by strokes
- Multiple sclerosis and others

What is physiotherapy and how can it help?

Physiotherapy is a form of treatment where practitioners use physical forms of treatment such as massages, exercises, heat treatment and other controlled forms of external stimuli to treat physical disorders.

This method of treatment can be very effective in correcting neurological disorders.

Some of the physiotherapy techniques, which can be implemented to help patients, are as follows:

Electrical Stimulation: This method is commonly used to treat muscular problems, especially incurred after an accident or any other form of injury. In this method, controlled electric stimulation is given to specific nerve areas over the skin to stimulate them.

Heat treatment: This method involves applying heat to parts of the body such as joints or muscles where there is nerve or muscular damage. This treatment is especially effective for muscle related problems.

Ice or cold treatment: Vertically opposite to the principle of heat treatment, ice or cold treatment is used to contract muscles within the body. This is especially effective where inflammation needs to be controlled.

Manual therapy: Possibly the most common form of physiotherapy, this method employs massages, pressure points, stretching and hands on strengthening exercises and helps regularize nerve impulses to areas where they have been affected.



How Physiotherapy Can Help with Neurological Disorders

Surgery to remove abnormal growths of the brain, peripheral nervous system or the spine or any disorder can be tricky because the brain and the skull that shields it are complex areas. In the old days, open surgery was the only way to access the brain or spinal cord. But, with the invention of laparoscopy, keyhole surgery to treat neurological issues is gaining ground.

What is Neuroendoscopy? 
Neuroendoscopy is a surgical procedure that is favoured by doctors and patients alike because it is minimally invasive.
Before the surgery, you will be administered general anaesthesia so that you will be unconscious during the entire duration. During the surgery, the surgeon will drill a minute hole into your skull just above the eyebrows. You skull also has two natural openings. That is why the surgeon may make use of the nose or the mouth to access the region that needs to be operated upon.

Neuroendoscopy is useful because -

  It lets the surgeon reach regions that are not accessible with open surgery
  The tumour can be removed without any damage being done to surrounding tissues

An endoscope is a delicate device with a high-resolution camera mounted on it. There is an eyepiece on the other end. The device is also fitted with a light. When it is inserted into the brain, it lights up the passage and the eyepiece allows the surgeon to take a look inside. The camera sends a live feed of the path it is traversing and this guides the surgeon. When the tumour is reached, it is gently removed with other surgical instruments that too were inserted through the cavities or the drilled hole.

Benefits of Neuroscopy -
There are several advantages of relying on laparoscopy -

  The patient endures less pain
  Fewer chances of infection
  Faster recovery
  Very little scarring of tissues

Which Disorders call for Neuroendoscopy?
Any of the following disorders can be put to rights with a neuroendoscopic surgery -

  Pituitary tumours
  Rathke s cleft cysts
  Pineal area tumours
  Ventricular tumours
  Skull base tumours
  Brain inflammation triggered by an infection
  Chordomas
  Cerebrospinal fluid fistulas
  Trigeminal neuralgia
  Cerebral aneurysm

After Surgery-
Once you undergo the neuroendoscopic surgery, you will have to be rehabilitated so that your condition can be monitored round the clock. Neuroendoscopy is a state of the art clean and efficient surgery that is beneficial to both surgeons as well as the patients.

Know More About Neuroendoscopy And Its Uses!

Neurological disorders are the diseases of the brain and spine, and the nerves which connect the brain and spine.

Some of the most common types of Neurological disorders are:

Alzheimer s Disease (AD)

Multiple Sclerosis

Epilepsy

Migraines

Parkinson s Disease

Ayurvedic Approach of Neurological Disorders

Ayurveda is an ancient system of medicine which originated in India, having a holistic approach to focus on treating the entire being. Ayurveda treatments are based on vata, pitta, and kapha doshas, whose balance leads to harmony and whose imbalance leads to toxic accumulations inside the body. Ayurveda aims to maintain an equilibrium among the three. It has effective solutions for a number of Neurological Disorders, also called  Vatavyadhi .

Eighty types of Vatavyadhi are described in Ayurvedic texts which can be placed under four categories: Kevala vata (Vata alone), Samsarga (Vata in association with Pitta and Kapha), Avarana (due to entrapment by other Dosha/Dhatu/Mala), and Dhatu Kshaya Janya (neurodegenerative). 

Ayurvedic Treatment

Ayurveda is plant-based systems of medicine. Because of being natural and harmless, it is very popular in treating various diseases. Several herbs have excellent properties to treat panic and anxiety affecting the central nervous system. Nature s gift of herbs and minerals not only alleviates symptoms but ensures cure by regulating neural biokinesis, thus preventing recurrence, relapse, and adversity.

Ayurveda can cure a number of Neurological Disorders like migraine, sinus, Parkinson s disease, anxiety, stress, insomnia, epilepsy, hysteria, cerebral palsy, stroke, etc. For treating these Neurological Disorders Panchakarma therapy is adopted which focuses on holistic treatment for long-lasting results.

Some of the common remedies under Panchakarma therapy are:

Chamomile tea, roots of kava, passion flower, ginseng, Cannabis sativa are all prescribed for anxiety.

Valerian is used as a natural sedative and for treating insomnia and panic attacks.

Ginkgo biloba and Hypericum perforatum have neuroprotective properties and are useful in treating learning dysfunction and improving memory.

Inhaling powder of seeds of Achyranthes aspera or Prickly chaff flower relieves from stiffness and migraine.

Bark powder of Acorus calamus or Sweet flag root enhances memory by curing forgetfulness. When consumed with honey, it is beneficial for anxiety and epilepsy. Equal weights of this powder with ginger powder is recommended for facial paralysis.

Powder of Malabar nut with honey cures epilepsy.

Seed powder of Siris tree is used for treating insanity, psychosis, anxiety, and hysteria.

Coriander extract relieves vertigo and headache.

Juice of Dodder plant or Amarbel is taken in water to improve brain disorders.

Extract of branches of peepal tree cures madness.

Decoction of roots of drumstick plant is given for epilepsy and hysteria.

Velvet bean is effective in treating Parkinson s disease.

Poppy is beneficial in sleeplessness, delirium, convulsion, etc.

Decoction of leaves of guava is used to cure physical and mental deformities.

Leaves of pomegranate, when concentrated in boiling water and given in warm milk, cures fatigue and insomnia.

Leaves of pomegranate and rose petals when concentrated in boiling water and given in ghee, cure madness.

Cloves paste in water is applied on earlobes to cure migraine.

Almonds improve memory, especially when taken at an early age.

Yoga and meditation help in improving mental health by incorporating discipline and relaxation.

Take Away

For reliable cure with minimal side effects, Ayurveda is very well developed for treating many brain-related disorders with an approach of maintaining equilibrium among the three doshas and towards holistic, long-term treatment.
